ELECTRlCALLY-PROPELLED VEHICLE.

Original application filed April 28, 1886, Serial No. 200,400. Dividedand application filed May 22, 1889, Serial No. 311,659.

Again divided and this application iiled July 16, 1890. Serial No.358,884. (No model.)

.T0 LZZ whom t may concern:

Be it known that I, RUDOLPH M. HUNTER, 'of thc city and countyofPhiladelphia, and State of Pennsylvania, have invented an Improvement inElectrically-Propelled Vehicles, of which the following is aspecification.

My invention has reference to electricallypropelled vehicles; and itconsists of certain improvements, all of which are fully set forth inthe following specification, and shown in the accompanying" drawings,whiclrform a part thereof.

This application (Case 154) is a division of my application (Case 9S)filed May 22, and No. 311,659, which in turn is a division ogsmyapplication No. 200,400, led April 2S, 1 6.

In carrying out my invention I have had the followingl objects in View,viz: Providing the car with a lighting-circuit in parallel with themotor which rotates the axle of the car and furnishing it with electriclamps; combining therewith a regulator on the car for controlling thecurrent passing to the motor independently of the current passing to thelighting-circuit, and also providing means for controlling the currentpassing through the lampsindependently of the motor; providing the motoror car with an electric bell or gong receiving current from themotor-circuit, and preferably arranged in a shunt around the motor, andcombined with a circuit-closer and signal cord, wire, or bar passingthrough the car, whereby a passenger may signal the conductor or driverto'stop the car; providing the vehicle or car with a shaft geared to theaxles, and two sets of motor-armature coils and commutators carried bythe shaft, and means to magnetize the said sets of armaturecoilssimultaneously 5 also, providing such motor devices with a regulatorcommon to both sets of armature-coils.

The foregoing is a brief enumeration of some of the most importantfeatures involved in carrying' out myinvention, and I will now refer tothe accompanying drawings, in which- Figure 1 is a sectional elevationthrough a car embodying my invention. view of same with the car-bodyremoved, and

Fig. 2 is a plan Fig. 3 is adiagram showing the arrangement of theelectric circuits on the car `or vehicle for lighting, signaling, andpropelling.

G is the car-body, and is supported upon springs g, which rest upon theaxle-boxes H, or a frame h secured to said axle-boxes.

K K are two motors having a common ar-V mature-shaft and carried by theframe h. The armature-shaft is provided with a Worm K', which gears intoa worm-wheel K2, secured upon the shaft K3, also carried by the frame h,and this shaft K3 is geared to the axles K by bevel-gears K4.

N is the motorcircuit receiving current from the line-conductors A,having a generator A2, or from a battery A carried by or moving with thecar. 'Any source of electric energy may be employed.

O is a variable resistance, which may be located in the motor-circuit.This resistancechan ging device or regulator controls the currentiiowing through the motor. By it the current flowing through both setsof armature-coils may be controlled.

The car is provided with electric lights E5, either small arc orincandescent, the latter being preferred, and these are connected inmultiple arc by wires e5 and conductors R, connected with themotor-circuit and preferably shunted around the motor. These eircuits emay have switches to cut out each lamp. The circuit R may include theheadlight E4, which may be either of the arc, large incandescent type,or a group of small incandescent. lamps. If the switch r is closed, thehead-light circuitwill be closed and the light continuous. Referring toFig. 3, it will be observed that when the circuits are coupled as shownthe head-light E alone will burn and its light will be continuous. If,now, switch lr be turned to break circuit R and include the circuit Rand its interrupter-switch R2, the head-light will be a dash-light. Ifthe switch lr be closed as before and the switch r2 turned to includecircuit E, then the incandescent lamps E5 will be` arranged in multiplearc with each other and in series with the are or head-light E. If it isdesired to burn the lamps E5 alone, the switch r is opened and switch r4closed in the circuit r3, connecting IOO lters Patent, is

the conductor E5 with circuit R, leading from the motor-circuit. If,now, the switch o" be closed t0 circuit, the head-light will be inmultiple-arc connection with the incandescent lamps, and if the switchis turned to circuit R', then the head-light will flash and theincandescent lamps burn continuously.

To accomplish the flashing of the headlight, I provide the circuit Rwith a circuitbreaker R2, which preferably closes by a spring action andis opened by a pin 7.52 on the car Wheel or axle or other moving part ofthe vehicle. As said pin moves around, it opens the circuit R',extinguishing the lamp, and as said pin passes the switch closes andre-estabLishes the circuit. I do not limit myself to any arrangement ofthe lamps on the car 0r to their particular circuits, and in place oftaking the current from the motor-circuit they may receive current fromseparate conductors, the essential feature of the invention being thelighting of an electric motor or car by electric lamps receivingelectricity from a common source with the motor.

S is a signal bell or gong to enable the passenger or conductor tonotify the driver or operator to stop the car, and receives its currentfrom a shunt-circuit s around the motor or from the motor-circuit. Aswitch s may be used to cut the signal out of circuit. Nermally, thebell is outof circuit, but by pulling upon a bell-rope S', ruimingthrough the car, the switch s? may be closed t-o signal the Operator tostop the car. The novelty in this arrangement consists in that thecurrent to operate the bell is received from the motorcircuit.

Broadly considered with reference to the lighting, signaling, and motorcircuits, it is immaterial to my invention what the source of electricenergy may be, as it may be carried by or with the car or received fromline-conductors, as desired.

Having now described my invention, what I claim as new, and desire tosecure by Let- 1. In an electricallypropelled vehicle, the combinationof a shaft geared to the axles,

two sets of armature-coils and their commutators carried by said shaft,and means to magnetize both of said sets of armature-coilssimultaneously.

2. In an electrically-propelled vehicle, the combination of a shaftgeared to the axles, two sets of armature-coils and their commutatorscarried by said shaft, means to magnetize both of said sets ofarmature-coils simultaneously, and eurrent-controlling devices carriedby the vehicle and common to both sets of armature-coils.

3. The combination of an electrically-propelled vehicle, a source ofelectrical energy, electric circuits between the source of energy andthe electric motor on the vehicle, and a current-regulating devicecarried by the vehicle for controlling the current passing to the motor.l Ll. The combination ol an electrically-propelled vehicle, an electricmotor coupled with the axle thereof, a source of electrical energy, alighting-circuit in parallel with said motor and receiving current fromthe same source of electrical energy, a regulator for controlling thecurrent passing to the motor independently of the current passing to thelightin g-eircuit, a series of electric lamps arranged in thelighting-circuit, and independent means for controlling the currentpassing through said lamps.

5. In an electric railway, the combination of the motor-circuitincluding the motor, a shunt-circuit around the motor and including anelectric belt, a circuit-closer adapted to make and break saidshunt`circuit, a switch to break said shunt-circuit and render itinoperative, and a signal cord passing into or through the car toactuate said circuitcloser for the purpose of signaling the operator tostop the car.

In testimony of which. invention I have hereunto set my hand.
